Embodiment Construction
[0019]As shown as FIG. 8, in this method for three-dimensional human pose estimation, including the following steps:[0020](1) establishing a three-dimensional human body model matching the object, which is a cloud point human body model of visible spherical distribution constraint.[0021](2) Matching and optimizing between human body model for human body pose tracking and depth point cloud.[0022](3) Recovering for pose tracking error based on dynamic database retrieval.
[0023]The invention takes the depth map sequence as the input, optimizes and matches with the established 3D human body model and the 3D point cloud transformed from the depth map. The optimization process combines the global translation transformation and the local rotation transformation, and uses the dynamic database to recover the pose when the tracking error occurs, finally realizes the fast and accurate pose tracking, and obtains the estimated position of the joint points from the human body model. So the real-ti...
